This invention relates to oil burners and aims to prevent waste of fuel, and to obtain a maximum amount'of available heat from a given quantity of fuel.

' r The invention supplies a burner of simple The burner includes an annular baflie, a

. cup within the annular-battle directly below the burner tip, a header above the burner tip and annular battle and having a centrally downwardly facing air outlet to supply air to the flame for promoting combustion, and a plurality of air pipes connected with the header, one of said pipes'receiving air from a blower, another extending to receive air from the outside, and another opening into the ash pit to draw a supply of air-therefrom.

embodiment of the invention it is to be understood that in adapting the means to meet specific needs and requirements, the design may be varied and changes in the minor details of construction may be resorted to withinthe scope of the invention as claimed, with out departing from the spirit thereof.

7 For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached, in which Figure 1 is a front view of a hydrocarbon burner embodying the invention, showing it applied to a furnace, the upper portion of which is broken away and the air pot thereof being in section.

Figure2 is a top plan view of the burner.

Figure 3 is a vertical, sectional view on the line 33 of Figure 2, looking in the direction of the arrows.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters. I

The numeral 1 denotes the body of a fur- While the drawings illustrate a preferred I nace or analogous type of heater, and 2 the grate thereof. The burner is shown sup-, ported upon the grate 2 or'other rest, and comprises a base plate 3 which is formed with a central depression 4 providing a sump to receive any overfiowof oil from the burner, A drain pipe 5 connects with thesump 4 to carry off any oil that mayfind'its way therein to a determinate point of discharge- Acup 5 is mounted upon the base plate 3 in line with the sump 4, and is spaced from the latter to admit of oil finding its way into the cup overflowing the same and reaching the sump 4 and passing off through the drain pipe 5.

An annular battle 6 is supported upon the base plate 8 concentric with the cup 5 and sump 4, and is provided in its sides with a plurality of openings 7 This baflie may be of any construction or suitable material capable of resisting heat. A header 8 is disposed some distance above the annular baffle 6 'and is provided witha downwardly facing outlet 9 to which is-fitted a collar 10 which terminates some distance above the plane of the upper edge of'the'bafi le 6. 'A plurality of short pipes 1 radiate from and form branches of the header. These branch pipes are designated by'the numerals11,12 and '13, respectively. A pipe 14 connects with the branch 11 and terminates a short distance be- 8 low the grate 2 so as to receive air from the ash pit of the furnace. A pipe 15 connects with the branch 12 and extends to the outside for receiving fresh air. A pipe 16 corresponding to the pipe 14 connects with the branch pipe 13, and terminates slightly below the grate 2 for receiving air from the ash pit of the furnace. The several pipes curve so as to offer a minimum resistance to the flow of air therethrough. An outlet is formed in the top of the header 8 in line with the opening 9.

A collar 17 is formed upon the inner wall, of l the header inline with the top opening and terminates in an inwardly directed flange or shoulder which supports a nozzle 18 which terminates at its lower smaller end a short distance from the collar 10. A curved pipe 19 connects with the opening formed in the top of the header 8. A pipe 20 connects witl the pipe 19 and leads to a suitable source of air supply, such as a blower, not shown.

A generator 21 is located above the plane of the header 8 and the branch pipes connected thereto and is of semicircular outline, as indicated most clearly in Figure 2 of the drawings. This generator consists of a tube which is closed at opposite ends. A pipe 22 from a suitable source of oil connects with one end of the generator 21. A pipe 23 connects with the opposite end of the generator 21 and is coupled to the burner tip 2% to convey the gaseous vapor from the generator to the burner tip. A pipe 25 also connects the delivery end of the generator 21 with the burner tip 24: and serves to drain any oil tendin to collect in the generator.

The burner, when installed, appears substantially as illustrated in the accompanying drawings. The burner is primed by supplying a small quantity of oil or other burning fluid to the cup 5 and igniting the same to heat the generator and other parts. After the generator has been sufficiently heated the oil supplied thereto by means of the pipe 22 is converted into vapor and passes from the generator through the pipe 23 to the burner tip 24 where it is ignited. Air under pressure from a blower, or other source, is supplied to the nozzle 18 by means of the pipes 19 and 20 and escapes through the collar 10 in a jet. This creates a suction through the header 8 and the various pipes connected thereto whereby air is drawn into the header through the pipes 15, 14;, and 16, and this air also discharges through the collar 10 and impingin upon the flame effects a spreading thereof through the openings 7 formed in the walls of the bafiie 6. Any carbon that may deposit upon the inner wall of the battle 6 is consumed and intensities the heat. Should the air supplied to the nozzle 18 fail from any cause the flame and heated condition of the parts will function to draw air through the several pipes 15, 14 and 16, as will be readily comprehended. Any oil tending to collect in the generator 21 will pass off through the pipe 25 into the burner 6, and any surplus will collect in the cup 5 and overflow the same into the sump 4 and pass therefrom through the drain pipe 5 to the determinate point of discharge.

Having thus described the invention, I claim:

1. A hydrocarbon burner including a base plate having a central portion depressed to provide a sump, a drain pipe connected with said sump, a cup supported upon the base plate in line with the sump and spaced therefrom, a burner tip located above the cup, means for supplying fuel to the burner tip and an annular bafiie supported upon the base late and surrounding the said cup and urner tip, and provided in its side walls with a plurality of flame outlets.

2. A hydrocarbon burner including a burner tip, a generator disposed above the burner tip within the heating zone of the flame and closed at opposite ends, a pipe connected with one end of the generator for supplying oil thereto, a pipe connected with the opposite end of the generator and with the burner tip for conveying gaseous vapor from the generator to the burner tip and another pipe between the delivery end of the generator and the burner tip for conveying surplus oil from the generator to the burner tip.

3. A hydrocarbon burner comprising a base plate, an annular baflie supported upon the base plate and provided in its side walls with a plurality of flame outlets, a burner tip within the annular bafiie, a header located above the burner tip and having alined openings in its top and bottom, air pipes leading from the header and passing through the base plate, one of said pipes extending to the outside and the others adapted to communicate with the ash pit, a nozzle fitted in the top opening of the header, a pipe connected to the nozzle for supplying air under pressure thereto, a curved generator tube disposed above the header and closed at opposite ends, means for supplying oil to one end of the generator and pipes connecting the opposite end of the generator to the burner tube for supplying gaseous vapor and surplus oil to the said burner tip.

4. A hydrocarbon burner comprising a base plate centrally disposed to provide a sump, a cup mounted upon the base plate in line with the sump and spaced therefrom, an annular baiile supported on the base plate and formed in its sides with openings, a burner tip within the baifle and aboy'e the cup, a header disposed above the bafile in line with the burner tip and having openings in its top and bottom, a nozzle connected with the top opening and terminating from the bottom opening of the header, air pipes grouped about the baflle and spaced therefrom and supported in the base plate and opening therebelow, one of the pipes connecting with the nozzle to supply air thereto under pressure, and the remaining pipes connecting with the header, a curved generator above the plane of the header and closed at its ends, an oil pipe connected with one end of the generator, a pipe connecting the top portion of the opposite end of the generator with the burner tip, and a second pipe connecting the lower portion of the generator with the burner tip.
